7.4.4.60.3 Properties
| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| ThermalTrippingUnitType | IfcPropertyEnumeratedValue | PEnum_ThermalTrippingUnitType |
A list of the available types of thermal tripping unit from which that required may be selected. |
|
| I1 | IfcPropertySingleValue | IfcReal |
The (thermal) lower testing current limit in [x In], indicating that for currents lower than I1, the tripping time shall be longer than the associated tripping time, T2. |
|
| I2 | IfcPropertySingleValue | IfcReal |
The (thermal) upper testing current limit in [x In], indicating that for currents larger than I2, the tripping time shall be shorter than the associated tripping time, T2. |
|
| T2 | IfcPropertySingleValue | IfcTimeMeasure |
The (thermal) testing time in [s] associated with the testing currents I1 and I2. |
|
| DefinedTemperature | IfcPropertySingleValue | IfcThermodynamicTemperatureMeasure |
The ambient temperature at which the thermal current/time-curve associated with this protection device is defined. |
|
| TemperatureFactor | IfcPropertySingleValue | IfcRatioMeasure |
The correction factor (typically measured as %/deg K) for adjusting the thermal current/time to an ambient temperature different from the value given by the defined temperature. |
|
| CurveDesignation | IfcPropertySingleValue | IfcLabel |
The designation of the trippingcurve given by the manufacturer. For a MCB the designation should be in accordance with the designations given in IEC 60898. |
